Question

four dinitrogen monoxide molecules
express your answer as an integer.

Explanation:

Step1: Determine the formula of dinitrogen monoxide

Dinitrogen monoxide has the chemical formula \( \text{N}_2\text{O} \). This means each molecule of dinitrogen monoxide contains 2 nitrogen atoms and 1 oxygen atom, so a total of \( 2 + 1=3 \) atoms per molecule.

Step2: Calculate the total number of atoms in 4 molecules

If one molecule has 3 atoms, then 4 molecules will have \( 4\times3 = 12 \) atoms.

Answer:

12
